INTRODUCTION: Appendicular actinomycosis is a rare disease produced by cecal appendix invasion by Actinomyces gender bacteria after a predisposing cause that disrupts mucosal barrier, such as acute appendicitis. The highest frequency appears in adults; however, there are cases in paediatric age described in literature. The aim of this article is to introduce a case of appendicular actinomycosis in a child with atypical presentation and to review the literature. CLINICAL CASE: 10-year-old boy transferred to our hospital due to intraoperative finding at a different centre of a right flank tumor, without identification of cecal appendix...

Actinomycosis is a relatively rare infection caused by Gram-positive bacteria. We present the case of a 54-year-old, previously healthy, male patient with a history of severe penicillin allergy who developed severe pneumonia and empyema caused by Actinomyces meyeri. Presenting symptoms included productive cough, right upper quadrant pain, and chills and rigors. He required drainage of the empyema via tube and prolonged antibiotic treatment with intravenous ceftriaxone for 2 weeks followed by oral doxycycline for 6 months...

Actinomycosis is a chronic suppurative granulomatous infection of subcutaneous tissues caused by bacterium Actinomyces israelii. It is a normal commensal of the oral cavity, gastrointestinal tract, respiratory tract, and vagina. Infection is first established locally by breach of mucosal barrier during various procedures, aspiration, trauma, or human bite. Rarely, it may spread through hematogenous and lymphatic system. We present a case of actinomycosis involving the vulva, extending to the inguinal region along with inguinal lymphadenopathy...

Actinomycosis is a rare, chronic granulomatous infection caused by gram-positive, anaerobic to microaerophilic branching filamentous bacteria. In the cervicofacial region, it usually presents as an enlarging neck mass. It remains a diagnostic challenge due to the fact that cultures show no growth in more than 50% of cases. We report a case of a 67-year-old patient known to have a neck mass secondary to lymphoma in which the neck mass persisted despite therapy. Upon evaluation, the diagnosis of culture-negative actinomycosis was based on histopathology findings, and the patient received antibiotic therapy...

Cervicofacial actinomycosis is today a rare disease in our country. Isolated neck swelling due to actinomycosis is extremely rare. A case of 52 year old man with an isolated neck swelling due to actinomycosis without any discharging sinus is reported here.

Actinomyces meyeri is a Gram positive, strict anaerobic bacterium, which was first described by Meyer in 1911. Primary actinomycotic osteomyelitis is rare and primarily affects the cervicofacial region, including mandible. We present an unusual case of osteomyelitis of a long bone combined with myoabscess due to A. meyeri. A 70-year-old man was admitted for pain and pus discharge of the right elbow. Twenty-five days before admission, he had hit his elbow against a table. MRI of the elbow showed a partial tear of the distal triceps tendon and myositis...

Actinomycosis is an infection caused by the actinomyces genus and is associated with trauma or previous infection. A 58-year-old male patient was referred from a private dental clinic for root extraction of the lower right molar. The x-ray showed fractured root-like material distal to the distal root of the lower right second molar. A biopsy during extraction of the root-like material was performed, which revealed a sequestrum with actinomycosis by a pathological examination. In this case, the radiopacity of the suspicious lesion was higher than that of the surrounding alveolar bone, which confused it with the root tip...

BACKGROUND Pelvic-abdominal actinomycosis is a rare chronic condition caused by an anaerobic, gram-negative rod-shaped commensal bacterium of the Actinomyces species. When Actinomyces becomes pathogenic, it frequently causes a chronic infection with granulomatous abscess formation with pus. Due to diversity in clinical and radiological presentation, actinomycosis can easily be mistaken for several other conditions. Peritonitis without preceding abscess formation caused by Actinomyces species has been described in only few cases before in literature...

BACKGROUND: Paediatric cervicofacial actinomycosis is a rare infectious disease caused by Actinomyces spp. and usually presents as a chronic, suppurative and granulomatous inflammation with a propensity to mimic malignant conditions. CASE PRESENTATION: We discuss the case of an 11-year-old African female who presented with a chronic disfiguring cervical mass evolving over a 9 months period for which she had several unyielding consultations. Appropriate clinical and para-clinical evaluations were paramount to the diagnosis of an Actinomyces infection...

BACKGROUND: Actinomyces, particularly Actinomyces israelii, may cause indolent, persistent infections or represent normal mucosal flora, leading to management dilemmas. MATERIALS AND METHODS: Prompted by a refractory Actinomyces meyeri infection complicating AIDS, clinical data for all Actinomyces isolates at our hospital laboratory since 1998 were analyzed. RESULTS: A total of 140 cases had a positive result for Actinomyces cultures. Of 130 cases with adequate follow-up, 36 (28%) cases had end-organ or disseminated disease treated with prolonged antibiotics or surgery or both (Group 1)...

UNLABELLED: Actinomycosis is a chronic suppurative infection, produced by anaerobic Gram-positive bacteria or microaerobic Actinomyces species. It is rare in children and adolescents and it is more common in immunocompromised. Mycobacterium tuberculosis collaborates on the development of the disease. Pulmonary involvement appears as a picture of chronic condensation that does not improve with conventional antibiotic treatment. Classic complications affecting the thoracic wall with drainage in «sulfur granule» and fistulization are described less frequently nowadays...

Actinomycosis is an infection of filamentous, gram-positive anaerobic bacteria. Actinomycosis of jaw bone is rare and the diagnosis is often difficult. The aim of this patient report is to present an actinomycotic osteomyelitis of mandible in a 30-year-old male patient. The patient presented with a chief complaint of pain and unhealed dental socket after mandibular teeth extractions. Radiographs showed ill-defined radiolucencies and perforation of buccal and lingual cortical plate; several biopsies and different therapy could not improve the lesion because of fault diagnosis and improper treatment...

Actinomycosis is a rare heterogeneous anaerobic infection with misleading clinical presentations that delay diagnosis. A significant number of misdiagnosed cases have been reported in specific localizations, but studies including various forms of actinomycosis have rarely been published.We performed a multicenter retrospective chart review of laboratory-confirmed actinomycosis cases from January 2000 until January 2014. We described clinical characteristics, diagnostic procedures, differential diagnosis, and management of actinomycosis of clinical significance...

Primary actinomycosis of breast is a rare disease with only a few cases reported in the literature. We present a case of a 25-year-old lactating woman with primary actinomycosis of breast which was diagnosed on cytology. The patient presented with lump in left breast with dull aching pain. Fine-needle aspiration cytology smears showed acute suppurative inflammation with presence of fluffy basophilic colonies on Hematoxylin and Eosin staining and branched, Gram positive filamentous bacilli on Gram staining. The bacilli were non-acid fast with 1% Zeihl Neelsen stain...
